Abstract: Disclosed are a hole transport layer including a thermally conductive inorganic structure, a perovskite solar cell including the same, and a method of manufacturing the same. The hole transport layer includes a thermally conductive inorganic structure including a plurality of nanoparticles and having pores surrounded by the nanoparticles and a hole transport organic material located in the pores, in which the nanoparticles include at least one inorganic material selected from the group consisting of a metal oxide and a metal nitride, whereby the hole transport layer not only effectively dissipates heat from the inside of devices but also avoids interfering with hole transport when applied to devices, thereby maintaining the high efficiency of solar cells and also greatly improving thermal and long-term stability thereof.

Abstract: Disclosed are an electron transport layer including a zwitterion layer, a solar cell including the same and a method of manufacturing the same. The electron transport layer includes a metal oxide layer including a metal oxide and a zwitterion layer formed on the metal oxide layer and including a zwitterion, thus exhibiting superior optoelectrical properties and stability. The solar cell includes the electron transport layer, thus solving hysteresis problems and exhibiting high photoelectric conversion efficiency and excellent resistance to various environmental factors (water, heat, light).
